If you live in (or near) a city center, you'll live in a large apartment building. If you want a single family house, you move outside the city center. You cannot have an urban city environment, with restaurants, bars, stores and walkable streets if you only have single family buildings with yards there. There is a place for everything, houses and large buildings. Otherwise, I agree with the comment above, that such buildings seem impractical, and can be replaced with separate buildings, even higher, with open space in between them (and greens and parks and benches,...), eg: https://goo.gl/maps/TneCupaRNq3SgQYL7 https://goo.gl/maps/TneCupaRNq3SgQYL7 (imagine this, but with undeground parking instead of cars parked on the steet).
